STEVEN BRENDZA, OF CLEVELAND, OHIO.

strain-CARPET EAs'rENEn.

Application filed. April 9, 1919.

To all whom it may concern:

Be it known that I, STEVEN BRENDZA, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Stair-Carpet Fasteners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates generally to carpet fasteners and more particularly to a device for fastening a strip of stair carpet to the stairs in such a manner that said stair carpet can be quickly and easily removed and replaced when desired.

Another object of the invention is to provide a stair carpet fastener embodying these advantageous features which will be ineX- pensive to manufacture and can be easily applied without the aid of a skilled mechanic.

With these objects in view the invention consists in the novel features of construction, combination and arrangement all of,

which be fully described hereinafter and set forth in the appended claims.

In the drawings forming a part of this specification Figure 1 is afront elevation of a portion of stairs with carpet applied thereto and secured by means of my im proved fastener; Fig. 2 is a detail sectional view on the line 22 of Fig. 1; Fig. 3 is a detail view illustrating the engagement of the hooked rod with the corner plate; and Fig. i is a detail view showing the corner plate and end of rod disconnected.

In the practical embodiment of my invention I employ a pair of apertured corner plates A which are adapted to be secured in the opposite angles of the stairs formed between the tread and riser and the stringer at the side thereof. These corner plates are preferably triangular in shape and are concavo-convex as shown, each plate being formed with a substantially cen tral aperture A through which a fastening screw B is adapted to be passed for the purpose of securing the plate in position. Each plate is also provided with an aperture G which is preferably arranged upon a line extending from the aperture A Specification of Letters Patent.

to the inner corner of the triangular plate A. The carpet to be secured is indicated at D and this is arranged in the usual manner upon the stairs and in order to secure this carpet properly in the angle between the tread and riser I provide a fastening means comprising a tube E and rods F, the inner ends of the rods fitting into the opposite ends of the tube E and the outer ends F of the rods are projected into the opening C and in order to prevent any lateral movement of these ends after having been properly positioned in the openings, I provide a shoulder or bend or upset portion F between the rod F and the extreme end F, this bend or upset portion being quite short so that the end F can be inserted into the opening C and then by proper manipulation the bend or upset portion F can be introduced into the opening thereby bringing the rod into locked engagement with the corner plate. I

In operation after the carpet has been properly arranged upon the stairs the rods are brought into engagement with the corner plates and then the tube or sleeve is brought into engagement with the inner ends of the rods practically making a continuous rod from corner to corner of the stairs and extending across the strip of carpet holding it properly positioned in the angle between the tread and riser.

When it is desired to remove the carpet it is only necessary to slip the tube or sleeve suiiiciently to one side to disengage-one of the rods and then the other rod can be quickly disengaged and the cap is entirely free to be removed. It will thus be seen that I provide an exceedingly simple and men'- pensive construction of staincarpet fastener capable of carrying out all of the objects hereinbefore referred to.

Having thus described my invention, what I claim is 1. In a stair-carpet fastener the combination with a pair of erforated corner plates, of rods having 1100 rod ends engaging said plates, and a tube connecting the opposed ends of said rods.

2. In a stair carpet fastener, the combination with rods having hooked outer ends, of

r a tube engaging the, inner ends of said rods, plates, of rods having their outer ends in and. means located at the opposlte sldes of engagement wlth said plates, and a tube enthe sta rs WIth. whlch the hooked ends of gaglng the opposed'ends of said rods.

the rods are engaged. I a p In testimony whereof I hereunto afiix my 10 5 3. In a stair carpet fastener, the combisignature,

nation with a pair of perforated corner I STEVEN BRENDZA.
